I still can occasionally, but not nearly like I could when I was younger. Hell even five years ago I could count on being able to cum at least two sometimes three times back to back without stopping.
The only good thing about growing old is that it beats the alternative.

oh my... the clit orgasms keep coming as long as "he" stays interested in pleasuring me. G-spotters, well that another matter. only experience them w/ an amazing lover - unfortunately, I've only had 1 - bah hum bug!!!

My wife can orgasm multiple times, more than 10-15 times if she wants to and she can orgasm quickly with any type of deep penetration, especially riding cowgirl. Other positions, she does not always orgasm as much, unless it is a toy. It doesn't have to do with the size of me so much as it has to do with where it is hitting during sex. For me, I usually only orgasm once, sometimes twice.

For my wife, typically at least 2 though she sometimes goes three or more, the most I can guess would be 6-7 when it has been a while and she is relaxed enough to just enjoy things. I have only had multiples a few times, tops was actually 3 and each one weaker than the previous, mostly I'm one and done though.

I get off super easy. During average sex, I can have 5-6. If he's wanting to push my limit, my top number right now is 47. IT also depends on the type of orgasms. I can have the most internal ones, and the fewest anal orgasms. My best ones are from masturbation.
